Not a lid. ### ⭐⭐⭐⭐⭐ Pasdt super *by B***B on 30 January 2026* Passt super, tolle Verarbeitung ### ⭐⭐⭐⭐⭐ Fit perfect on hydro flask bottle *by M***! on 13 July 2023* Fit hydro flask bottle (medium tall skinny size) perfectly! My daughter’s bottle is black and we switched it up 1. because she dropped hers outside on playground and one side shattered off and 2. because someone else had the same exact bottle/size/color. Now we know which one is hers. I chose fuscia and it looks so cute. She loved it. ## Frequently Bought Together - Hydro Flask Standard Mouth Lids- Accessory for Standard Mouth Water Bottle - Auto Flip Lid for Hydro Flask Standard Mouth Bottle, Spout lid for Iron Flask, Fits for Simple Modern and Most Brands, Replacement Lid with Button Lock, Black - Hydro Flask Flex Boot - Accessory Silicone Water Bottle Protector - Dishwasher Safe, BPA-Free, Non-Toxic Small --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/263915102-hydro-flask-flex-cap-standard-mouth-leak-proof-with-honeycomb](https://www.desertcart.com.ar/products/263915102-hydro-flask-flex-cap-standard-mouth-leak-proof-with-honeycomb) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-08*
